In short: A tip calculator works out the tip and total for a bill at a chosen percentage and splits it between people; 15–20% is customary for US restaurant service.
About Tip Calculator
At the end of a meal nobody wants to do mental arithmetic. Enter the bill, choose a tip percentage and the number of people, and this calculator shows the tip, the total, and what each person owes.
Tipping customs vary a lot by country: in the United States 15–20% at sit-down restaurants is customary, in much of Europe service is often included and rounding up is common, and in Japan tipping is generally not expected. Adjust the percentage to match the local norm. The round-up option gives everyone a clean whole-number share, with the extra going to the tip.
How to use Tip Calculator
- Enter the bill amount (before or after tax, depending on local custom).
- Choose a tip percentage or tap a quick button.
- Enter how many people are splitting.
- Read the tip, total and per-person share. Tick round-up for easy cash amounts.
Examples
Bill 86.40, tip 18%: tip 15.55, total 101.95, each person pays 33.98.
With round-up, each pays 34.00, so the total becomes 102.00 and the tip 15.60.
Frequently asked questions
Should I tip on the amount before or after tax?
In the US, many people tip on the pre-tax amount, though tipping on the total is common and simpler. Either is acceptable.
Is service included?
Check the receipt for “service charge” or “gratuity”. If it is already included, an extra tip is optional.
How are rounding pennies handled?
Without round-up, shares are rounded to the cent and the last cent differences are noted.
Does it support other currencies?
Yes — the numbers work for any currency with two decimal places.
